1221406-25-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1221406-25-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,4,0 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1221406-25:
(9*1)+(8*2)+(7*2)+(6*1)+(5*4)+(4*0)+(3*6)+(2*2)+(1*5)=92
92 % 10 = 2
So 1221406-25-2 is a valid CAS Registry Number.
